Description

Technical Field

[0002] The launch pad is used to support and secure the vehicle, perform vertical adjustment, azimuth aiming, install fire protection pipes and ignition circuits, and ignite the launch. During launch, the gas flows through the flame exhaust hole in the center of the launch pad, into the guide groove under the pad, and is discharged to both sides.

[0003] The launch pad is an important component of the ground equipment of the carrier rocket. During the preparation before and during the launch of the rocket, it supports the rocket vertically, adjusts the verticality of the rocket according to the requirements of the rocket control system, and cooperates with the aiming equipment to complete the rocket's aiming and certain auxiliary tasks.

This resulted in low work efficiency, high labor intensity, low control accuracy, and high risk. Moreover, during the lifting, transportation, and erection process, any slight deviation in the docking position would require a slight movement or rotation of the carrier, which was time-consuming and labor-intensive.
